Hi all, a good friend of mine (honest, it wasn't me!) accidentally poured water into the engine oil compartment instead of the compartment where water goes! It's an unfortunate mistake and sadly can happen in a rush.

So I was hoping someone may have experienced this before and can offer any suggestions. I imagine the independent garages should be able to deal with this.

Any idea of the cost and the likely course of action?

Many thanks in advance for your help.

The car is a 2007 Cayman.

If he didn't start the engine it should be a straight forward drain, flush and refill.

As above get it towed to a garage flush & refill then do the same again in 1000 miles just to make sure it's ok.

It's actually my car. Just to clarify further I filled the oil tank right to the top with water and started the car. It ran for 3-4 seconds, lost power and shut off.

I then started it again and it turned off within 1 second at which point I realised what I had done.

I have drained all the water and oil from the engine. There was some water and oil in the air filter (just across the bottom third of the filter) which I have also dried out.

I haven't done anything else so any help would be greatly appreciated. Thanks

Just how much water did you put in to fill that to the top???

If it just turned over on the starter motor and fired for a few secs you may be OK.
Drain. New filter. Refill. Any water left in the system won't be too much of a problem given the volume of fresh oil, but maybe a second empty and refill after warming it through (oil normally has some water in it from condensed vapour from combustion on short journeys).
That is assuming it starts OK...

All you can do really is to drain it all out, fit a new filter and fill it with flushing oil. Run the engine as per the oil manufacturer's instructions, and then drain and fit a further new filter and fill with regular oil. If it doesn't make any nasty noises and you don't get any CEL warnings, you should be ok.

Aren't the early Cayman engines iffy anyway? Good opportunity for a rebuild!

Started and cut-out doesn't sound good. If you do get it going, delete this thread and sell it quick.

By filling it with fluids to this level and tuning it over you have certainly put pressures on the engine internals that it should not have, the fact you had fluids in the air filter means you have them in the intake system, which can bend valves, con rods, etc. Having said that we saw one in a similar position in our workshop a few years ago and it was fine after a careful clean up an still runs well to this day.

If you are not mechanically confident, take it to a dealer/ independent and let them sort it out. If however your are happy to do it yourself you could fill it with fresh oil and oil filter, take all the spark plugs out and then turn the engine manually by hand for a few rotations to gently push fluids out of the intake and cylinders. Assuming it turns freely and no more fluid is coming from the plug chambers then you should be fine to spin it over with no plugs in order to push out any remaining fluids; after this I would run a compression check to make sure you haven't done and damage. The one we had in also had fluid in the exhaust, so before we could put spark plugs in and start it up we dropped the exhaust system off and drained it out, worth checking to make sure it hasn't leaked through into the exhaust. When they are overfilled the boxer engines can let fluids into the combustion chambers and if the exhaust valves are open it finds its way into the exhaust, if the inlets are open into the inlet side of the engine.

It'll probably smoke a bit when you alert it up so have it somewhere well ventilated and let it idle for a while, monitor pressures and temperatures while the smoke clears out of the exhaust, this can take a good while! If it is OK after idling take it for a gentle run and see how it runs.

Assuming it runs ok I would drop the oil again after 50 miles and see how it looks.

Hopefully you'll be ok

Excellent advice - I missed the fact that you were talking about the air filter and assumed it was the oil filter that had water in it. Shall stick to medicine wink

Thank you for your kind and detailed advice. Would it be possible to get in touch with you?

22 litres of water !

Hope you get it sorted, pulling the spark plugs is good advice. I hydrolocked a company car many years ago when attempting to set a new team splash record at a local ford. Very similar outcome to yourself but once it finished squirting water out of spark plug holes it was fine .....,. I think. biggrin

Easy fix.

Buy an air cooled.

My 996T has ~9 litres of oil, 28 litres of coolant. You can't have poured 22 litres of water into the oil filler.

9 litres is just the sump and lines. The engine could take far more than 22 litres of water!

This turned out to be (very successful) trolling, from what I recall.

Yes, because all the oil will be on the driveway :-)
